Reviews Praseodymium Yttrium Alloy

Bosch Automotive (7424) OE Fine Wire Double Platinum Spark Plug - Pack of 10

Revolutionary surface air gap firing technology featuring four yttrium-enhanced ground electrodes delivers the longest, most powerful spark for ultimate engine performance.
Four yttrium-enhanced ground electrodes provide optimum access to the air/fuel mixture for the most efficient combustion, plus the yttrium alloy ground electrodes reduce gap wear and oxidation for extended performance life.
Electrode gap is factory set to provide ease of installation - never requires adjustment.
Never requires gapping, the electrode gap is factory-set and never requires adjustment.
Provides ease of installation - never requires adjustment.

Full platinum tip ensures virtually no gap erosion for long plug life.
Yttrium enhanced, high nickel alloy side electrode maintains precise gap to increase plug life.
Necked-down center electrode fires quicker and cleaner, with less voltage for easier starts, quicker acceleration, and improved fuel economy.
Platinum alloy pad on ground electrode provides extended durability and service life and platinum-to-platinum firing.
Nickel-plated steel shell for long-life corrosion resistance.
